Description

  The present invention relates to a central device, a peripheral device, a communication system, a communication method and a program.

In recent years, communication terminals equipped with BLE (Bluetooth Low Energy, Bluetooth is a registered trademark), which is one of short-range wireless communication, are in widespread use (see, for example, Patent Document 1). BLE is a wireless technology developed for low power consumption communication.
The transfer of data by BLE is basically performed based on a profile called GATT (Generic Attribute Profile). In GATT, one or more characteristics are grouped as a service. A terminal that defines a service is called a server (Server), and a terminal that calls a service is called a client (Client), and the client receives data according to the characteristic declarations defined in the server. For example, giving the role of a client to an information communication terminal such as a smart phone and the role of a server to a biological information measuring device etc, and representing communication rules between communication terminals such as encryption using characteristics as a key for data transfer. Can.

  Further, in BLE, GAP (Generic Access Profile), which is a general-purpose access profile for mutually communicating between communication terminals, is defined. For example, the role of a central apparatus (Central) in an information communication terminal such as a smartphone is defined. By defining the role of the peripheral device (Peripheral) in the biological information measuring device, etc., discovery and connection of the peripheral device can be performed quickly and quickly.

  BLE supports security mechanisms such as communication encryption as standard. GAP is built on Security Management Protocol (SMP) which is a protocol for security, and it is possible to set security such as presence / absence of encryption through GAP. When encrypted communication is required, communication needs to be performed using the generated encryption key.

  The biological information measurement device 10 provides three services having different encryption methods as services available for communication with the communication terminal 20. That is, the biological information measurement device 10 provides the first service, the second service, and the third service. Each service includes a receiving characteristic for the communication terminal 20 to receive biological information from the biological information measuring device 10, and information used for measuring biological information from the communication terminal 20 to the biological information measuring device 10 (for example, height) Transmission characteristic for transmitting (eg, age, etc.). Note that different communication rules are defined for each characteristic. The communication related to each service is the first service is the most secure, then the second service and then the third service in order.

The first service has a first receiving characteristic and a first transmitting characteristic.
The first receiving characteristic receives a transmission request of the target information from the communication terminal 20 by communication encrypted by the BLE key, and notifies the communication terminal 20 of the target information by communication encrypted by the BLE key. That is, the first reception characteristic has a value attribute set for encrypted communication and a CCCD (Client Characteristic Configuration Descriptor) set for encrypted communication. The CCCD is a value indicating whether to notify the communication terminal 20 of the target information. When the value of CCCD indicates 1, it means permission to notify the object information. When the value of CCCD indicates 0, it means that the notification of the object information is prohibited.

The communication terminal 20 includes a terminal information storage unit 21, a communication unit 22, and an application unit 23 as functions of the OS.
The terminal information storage unit 21 stores an attribute of the communication terminal 20. The attribute of the communication terminal includes the model (model number) of the communication terminal 20, the type of OS installed in the communication terminal 20, and the version of the OS. Hereinafter, a combination of the model (model number) of the communication terminal 20, the type of OS, and the version of the OS is referred to as terminal information.
The communication unit 22 has a communication function by BLE.
The application unit 23 executes an application program that is optionally installed by the user.

The application unit 23 includes a terminal information acquisition unit 31, a mapping storage unit 32, a service specification unit 33, and a communication control unit 34 by executing a biological information reception program for receiving biological information from the biological information measurement apparatus 10. .
The terminal information acquisition unit 31 acquires terminal information from the terminal information storage unit 21. The terminal information acquisition unit 31 is an example of an attribute acquisition unit that acquires attribute information indicating an attribute of the own device.
The mapping storage unit 32 stores mapping information in which the UUID of the service used for communication with the biological information measuring device 10 and the terminal information are associated. The relationship between the terminal information and the service is specified by the connection test in advance.
Among the services provided by the biological information measurement device 10, the service identification unit 33 identifies a service that can communicate with the device itself. That is, the service specifying unit 33 specifies the receiving characteristic and the transmitting characteristic which can communicate with the own apparatus. The service identification unit 33 is an example of a communication rule identification unit.
The communication control unit 34 receives the biological information from the terminal information storage unit 21 based on the service specified by the service specifying unit 33.

Next, a notification method of biological information by the communication system 1 according to the present embodiment will be described.
FIG. 2 is a sequence diagram showing a method of communicating biological information according to the first embodiment.
The communication control unit 13 of the biological information measuring device 10 transmits an advertising packet notifying of the presence of the own device at a constant cycle via the communication unit 12 (step S101).
When the communication unit 22 of the communication terminal 20 receives the advertising packet of the biological information measuring device 10, the communication control unit 34 transmits a connection request packet to the biological information measuring device 10 via the communication unit 22 (step S201). Thus, communication between the biological information measuring device 10 and the communication terminal 20 is established.

  Next, the terminal information acquisition unit 31 acquires terminal information stored in the terminal information storage unit 21 (step S202). Next, the service specifying unit 33 specifies the UUID of the service stored in the mapping storage unit 32 in association with the acquired terminal information (step S203). Next, the communication control unit 34 searches for a characteristic included in the identified service (step S204). When the communication control unit 13 of the biological information measuring apparatus 10 receives the characteristic search via the communication unit 12, the communication characteristic of the reception characteristic and the transmission characteristic belonging to the service to be searched is used as the communication terminal. It transmits to 20 (step S102). Thereby, the communication terminal 20 can specify the UUID of the reception characteristic and the transmission characteristic included in the specified service.

  Next, the communication control unit 34 rewrites the CCCD of the identified reception characteristic to 1 via the communication unit 22 (step S205). As a result, the biological information measurement apparatus 10 can be notified of the biological information to the communication terminal 20 by the reception characteristic. Next, the communication control unit 34 transmits the information used for measuring the biological information to the biological information measuring device 10 via the communication unit 22 based on the specified transmission characteristic (step S206). At this time, the communication unit 22 writes to the transmission characteristic based on the communication rule defined in the transmission characteristic. Next, the communication control unit 34 waits for notification of the biological information by the biological information measurement device 10.

The biological information measurement device 10 monitors CCCDs of all the receiving characteristics, and specifies the receiving characteristics used for the notification of the biological information (step S103). That is, the biological information measuring device 10 specifies the receiving characteristic in which the value is written to the CCCD as the receiving characteristic to be used for the notification of the biological information.
Next, the measurement unit 11 of the biological information measurement device 10 measures the biological information of the user using the received information (step S104). The communication control unit 13 stores the biological information measured by the measurement unit 11 in the value attribute of the reception characteristic that is specified in step S103. Since the CCCD of the reception characteristic is rewritten to 1 in step S206, the communication unit 12 notifies the communication terminal 20 of the biological information based on the reception characteristic (step S105). Thus, the biological information measurement device 10 can notify the communication terminal 20 of biological information based on the communication rule corresponding to the terminal information of the communication terminal 20.

When the communication control unit 34 of the communication terminal 20 receives the notification of the biological information from the biological information measurement device 10, the CCCD of the reception characteristic identified by the search in step S204 is rewritten to 0 via the communication unit 22 (0 Step S207). As a result, the biological information measurement device 10 does not notify the communication terminal 20 of the biological information by the reception characteristic. Then, when the user leaves the biological information measurement apparatus 10 and the communication terminal 20 goes out of the communication range of the biological information measurement apparatus 10, the communication between the biological information measurement apparatus 10 and the communication terminal 20 is disconnected.
According to the above procedure, the communication terminal 20 can receive the biological information from the biological information measuring device 10.

Here, a method of creating the mapping information stored in the mapping storage unit 32 will be described.
FIG. 3 is a flowchart showing a method of creating mapping information according to the first embodiment.
The designer of the biometric information reception program executes the processing described below using a plurality of communication terminals 20 having different terminal information. First, the designer tries to connect the communication terminal 20 and the biological information measuring device 10 by the first service (step S301). The designer determines whether communication between the communication terminal 20 and the biological information measuring device 10 has succeeded based on the connection log of the communication terminal 20 (step S302). When the communication between the communication terminal 20 and the biological information measuring apparatus 10 is successful (step S302: YES), the designer associates the mapping information with the terminal information of the communication terminal 20 and the UUID of the first service. Is added (step S303).

  When communication by the first service between the communication terminal 20 and the biological information measuring apparatus 10 fails (step S302: NO), the designer connects the communication terminal 20 to the biological information measuring apparatus 10 by the second service. An attempt is made (step S304). The designer determines whether the communication between the communication terminal 20 and the biological information measuring device 10 has succeeded based on the connection log of the communication terminal 20 (step S305). If the communication between the communication terminal 20 and the biological information measuring device 10 is successful (step S305: YES), the designer associates the mapping information with the terminal information of the communication terminal 20 and the UUID of the second service. Is added (step S306).

When communication by the second service between the communication terminal 20 and the biological information measuring apparatus 10 fails (step S305: NO), the designer uses the terminal information of the communication terminal 20 and the UUID of the third service in the mapping information. And the information associated with each other is added (step S307).
According to the above-described procedure, the UUID of the most secure service among the services that can connect the biological information measurement device 10 and the communication terminal 20 is recorded in the mapping information.

  As described above, according to the present embodiment, the communication terminal 20 is a service specification that specifies a communication rule to be used for communication with the biological information measuring apparatus 10 from among a plurality of communication rules indicating different encryption methods using BLE keys. And a communication unit 22 that receives biological information from the biological information measuring device 10 based on the communication rule. Accordingly, the communication terminal 20 can receive the target information from the biological information measurement device 10 by using one of the plurality of communication rules that can communicate with the biological information measurement device 10. Further, by preparing a plurality of communication rules having different encryption methods, the communication system 1 can support the exchange of biometric information by encrypted communication.

  Also, the communication terminal 20 according to the present embodiment receives the biometric information using the service that the mapping storage unit 32 stores in association with the terminal information of the own device. As a result, the communication terminal 20 can easily identify the service that can be connected to the biological information measurement device 10.

  Further, the biological information measurement device 10 according to the present embodiment supports three services consisting of a first service, a second service, and a third service. The first service encrypts a notification instruction of biological information with the BLE key and transmits it to the biological information measuring apparatus 10, and the communication information measuring apparatus 10 encrypts the biological information with the BLE key and transmits it. It is a service. The second service transmits the notification instruction of the biological information to the biological information measuring apparatus 10 without encrypting it with the BLE key, and the biological information measuring apparatus 10 encrypts the biological information with the BLE key and transmits it. It is a defined service. The third service is a communication in which a notification instruction of biological information is transmitted to the biological information measuring apparatus 10 without encryption using the BLE key, and the biological information measuring apparatus 10 transmits the biological information without encryption using the BLE key. It is a service that defines the rules. Thus, the biological information measurement device 10 can reliably notify the communication terminal 20 of the biological information.

  Although the mapping storage unit 32 according to the present embodiment associates and stores the terminal information with one of the first service, the second service, and the third service, the present invention is not limited to this. For example, the mapping storage unit 32 may store only the terminal information connected by the first service or the second service in association with the service. In this case, when the terminal information of the own device is not stored in the mapping storage unit 32, the service specifying unit 33 specifies the third service as a service to communicate with the biological information measuring device 10.

Second Embodiment
The second embodiment will be described.
FIG. 4 is a schematic view showing the configuration of the communication system according to the second embodiment.
According to the communication system 1 according to the first embodiment, when the biological information measurement device 10 and the communication terminal 20 are connected by the third service, the biological information is transmitted in plain text. On the other hand, since biometric information is personal information of a user, it may be desired to be transmitted by encrypted communication. On the other hand, according to the communication system 1 of the second embodiment, the biometric information is encrypted and transmitted regardless of which service the biometric information measuring device 10 and the communication terminal 20 are connected to. .

According to the communication system 1 of the second embodiment, the biological information measurement device 10 includes the encryption processing unit 14, and the communication terminal 20 includes the encryption processing unit 35.
When the biological information measuring apparatus 10 and the communication terminal 20 are connected by the third service, the cryptographic processing unit 35 measures biological information by a predetermined method (for example, common key method and public key method). Encrypt the information used. The communication control unit 34 stores the encrypted information in the third transmission characteristic, when the biological information measurement device 10 and the communication terminal 20 are connected by the third service. The encryption processing unit 14 decrypts the encrypted biological information received by the communication control unit 34 according to a predetermined method.
Further, when the biometric information measuring device 10 and the communication terminal 20 are connected by the third service, the encryption processing unit 14 encrypts the biometric information by a predetermined method. The communication control unit 13 stores the encrypted biometric information in the third reception characteristic when the biometric information measuring device 10 and the communication terminal 20 are connected by the third service. The encryption processing unit 35 decrypts the encrypted biological information received by the communication control unit 34 according to a predetermined method.
Thus, the communication system 1 can encrypt the transmitted and received biological information even when communication using encryption with the BLE key is not possible.

  On the other hand, when the biological information measuring device 10 and the communication terminal 20 are connected by the first service or the second service, the information and the biological information used for measuring the biological information are encrypted by the BLE key, so that the encryption process is performed. The encryption by the unit 14 and the encryption processing unit 35 is not performed. Thereby, the biometric information measuring device 10 can suppress the calculation load by the cryptographic processing unit 14 and the cryptographic processing unit 35 when connected by the first service or the second service.

As described above, the biometric information measurement device 10 according to the present embodiment can encrypt and transmit biometric information regardless of which service the communication terminal 20 is connected to.
In the present embodiment, when the biological information measurement apparatus 10 and the communication terminal 20 are connected by the third service, encryption is always performed by the encryption processing unit 14 and the encryption processing unit 35, but the present invention is limited thereto. I can not. For example, the biometric information measuring apparatus 10 according to another embodiment receives an input of necessity of encryption from the user, and determines whether to perform encryption by the encryption processing unit 14 and the encryption processing unit 35 based on the input. You may judge. The input of the necessity of encryption is made, for example, by writing to the transmission characteristic.

Third Embodiment
The third embodiment will be described.
FIG. 5 is a schematic view showing the configuration of the communication system according to the third embodiment.
The communication terminal 20 according to the first and second embodiments specifies a service used for communication with the biological information measurement device 10 based on the model information stored in the mapping storage unit 32. On the other hand, the communication terminal 20 according to the third embodiment specifies a service used for communication with the biological information measuring device 10 without using the mapping information.

  The communication terminal 20 according to the third embodiment includes a service transmission unit 36 in addition to the configuration of the first embodiment. The communication terminal 20 according to the third embodiment differs from the first embodiment in the operation of the service identification unit 33. The communication terminal 20 according to the third embodiment does not include the mapping storage unit 32.

The service specifying unit 33 attempts connection by the first service, and specifies the first service as a service to be used for communication with the biological information measuring apparatus 10 when data exchange is successful. If transmission / reception of data by the first service fails, the service specifying unit 33 attempts connection by the second service, and if transmission / reception of data succeeds, the second service is exchanged with the biological information measuring device 10. Identify as a service used for communication. When the exchange of data by the second service has failed, the service specifying unit 33 specifies the third service as a service to be used for communication with the biological information measuring device 10.
The communication control unit 34 receives the biological information from the biological information measuring device 10 using the service specified by the service specifying unit 33 according to the above procedure.
As a result, the communication terminal 20 according to the present embodiment can specify the service used for communication with the biological information measurement device 10 without using the mapping information.

  The service transmission unit 36 associates the UUID of the service identified by the service identification unit 33 with the terminal information acquired by the terminal information acquisition unit 31, and transmits it to a server apparatus (not shown) connected via the network. Thus, the designer of the biometric information receiving program can generate the mapping information using the information stored in the server device.

  Although the communication terminal 20 according to the present embodiment associates the UUID of the service with the terminal information and transmits it to the server device, the communication terminal 20 according to another embodiment may not transmit the information.

  Moreover, although the communication terminal 20 which concerns on this embodiment is not provided with the mapping storage part 32, it is not restricted to this. For example, as in the first embodiment, the communication terminal 20 according to another embodiment attempts to specify a service based on the mapping information stored in the mapping storage unit 32, and the service associated with the terminal information of the own device If not, the service specifying unit 33 may specify the service in the above procedure.

As mentioned above, although one embodiment was described in detail with reference to drawings, a concrete configuration is not restricted to the above-mentioned thing, It is possible to do various design changes etc.
For example, although communication system 1 concerning an embodiment mentioned above explained a case where living body information measuring device 10 operated as a peripheral device, it is not restricted to this. For example, in another embodiment, a device that notifies information other than biological information, such as a position information notification device or a beacon device may operate as a peripheral device.

  Moreover, although the biometric information measuring apparatus 10 and the communication terminal 20 which concern on embodiment mentioned above communicate by BLE, it is not restricted to this. For example, the biological information measurement device 10 and the communication terminal 20 according to another embodiment may perform communication according to another communication method in which communication in accordance with a predetermined communication rule is performed in the biological information measurement device 10.

  The communication system 1 according to the above-described embodiment includes the mapping storage unit 32 in the communication terminal 20, and identifies the service used for communication between the biological information measurement device 10 and the communication terminal 20. However, the present invention is not limited thereto. For example, in the communication system 1 according to the other embodiment, the biological information measuring device 10 includes the mapping storage unit 32, and the communication terminal 20 notifies the biological information measuring device 10 of the terminal information, whereby the biological information measuring device 10 operates. You may specify a service. In this case, when the biological information measuring device 10 notifies the communication terminal 20 of the UUID of the service, the service specifying unit 33 of the biological information measuring device 10 can specify the service used for communication.

  Further, in the biological information measurement apparatus 10 according to the above-described embodiment, each service that defines different communication rules has one transmission characteristic and one reception characteristic, but is not limited thereto. For example, the biometric information measuring apparatus 10 according to the other embodiment provides two services of a service for transmission and a service for reception, and each characteristic for transmission belongs to the service for transmission, and each characteristic for reception is It may belong to the service for reception. In the biological information measurement apparatus 10 according to another embodiment, all the characteristic may belong to one service.

  In addition, the biological information measurement device 10 according to the embodiment described above includes three types of reception characteristics of the first reception characteristic, the second reception characteristic, and the third reception characteristic. To provide, but not limited to. For example, the biological information measurement device 10 according to another embodiment may provide four or more types of reception characteristics, or may provide two types of reception characteristics.
